Answer:
Option A.
Step-by-step explanation:
Circle contains all points in a plane that are equidistant from a point, i.e., center of the circle.
The locus of points 9 units from the point (-1,3) on the coordinate plane.
It means, the figure represents the set of all points which are 9 units from the point (-1,3).
So, the given describes a circle with of 9 units and center at (-1,3).
Therefore, the correct option is A.
The area of this shape is 20 unit².
<h3>What is the area of the shape?</h3>
The total number of unit squares in the shape is the area of the shape.
Given in the figure:
The number of complete squares in the shape = 12
The number of squares more than half in the shape = 8
The total number of squares in the shape = 12 + 8 = 20
Area of the 1 square = 1 unit × 1 unit = 1 unit²
Area of 20 squares = 20 × 1 unit = 20 unit²
Approximate area of the shape = 20 unit²
Therefore, the area of the given shape is 20 unit².

We can solve this by looking at pairs that equal 60.
6 and 10 get to 60 when multiplied. Let's see if it fits in as a perimeter.
12+20=32
So the width and length of the room is 6 meters and 10 meters.
Answer:
x = 
or 0.706
or 1.735
Step-by-step explanation:
5x + 2y=7 ----->(eq 1)
- 2x + 6y=9 ----->(eq 2)
Multiply (eq 1) with 3
3×(5x + 2y) = 3×7
15x + 6y = 21 ----->(eq 3)
substract (eq 3) from (eq 2)
- 2x + 6y - (15x + 6y) = 9-21
- 2x + 6y - 15x - 6y = 9-21
- 2x - 15x + 6y - 6y = 9-21
-17x = -12
x = -12 ÷ -17
x =
put x = in (eq 1)
